celebrated for its wine, is perched on an eminence 1730 feet high. It was a great stronghold of the Orsini, and afterwards of the Colonnas, whose towers and palace still stand. The principal street is the Corso. At the top, on the right hand side, is a house decorated with curious mosaics and bas-reliefs, surmounted with a Madonna. At the bottom of the Corso is the Cathedral of S. Barnabas, in which is a picture of S. Bartholomew, by Guercino. The fountain close by is picturesque, composed of half female figures supporting the basin, out of which four figures rise supporting a column. _Over a beautiful route of four miles we reach_ GROTTA FERATTA, AND CICERO'S TUSCULAN VILLA, which is now a Greek monastery, founded in 1002 by S. Ninus. In one of its chapels are frescoes from the life of the saint, by Domenichino, restored by Camuccini in 1819. Fairs are held here on the 28th of March and 8th of September, drawing large crowds from the neighbourhood as well as from Rome. The villa stands on the site and is built out of the remains of Cicero's Villa, which he purchased of Sylla the dictator at a great price. To the south of the hill upon which the villa stands is a deep dell, falling into which is the stream of the Aqua Craba, mentioned by Cicero, now called the Maranna or running stream; and the plane-tree still flourishes here as it did in his day. Cicero likewise mentions that he had statues of the muses in his library, and a hermathena in his academy, and these statues were actually found here. The scenes of his "De Divinatione" and "Tusculan Disputations" were laid here. They were not addressed to any public assembly, but he used to retire after dinner to his so-called academy, and invited his guests to call for the subject they wished explained, which became the argument of the debate. These five discussions or conferences he collected and published as the "Tusculan Disputations" after the name of his villa, which was in the Tusculan territory, but not at the city itself. The subjects were,--Contempt of Death; On Bearing Pain; Grief of Mind; Other Perturbations of the Mind; Whether Virtue be Sufficient for a Happy Life. It was here that he received news of his proscription. A pleasant drive soon brings us to the foot of the hills, passing on our way several tombs, and the ruined castle of the Savellis, a medieval stronghold of the tenth century, called BORGHETTO, of which only the outer walls are standing. Two miles below, _on our right_, are the ruins of an immense reservoir of the aqueducts coming from the Alban Hills, the TEPULA, 126 B.C.; the JULIA, 34 B.C.; and the SEVERIANA, 190 A.D. It is known by the name of the CENTRONI. Just below the bluff on which it stands, the stream of the Aqua Craba, coming from Rocca di Papa, falls into the Almo coming from Marino; united, they flow through an old tunnel under the road beyond the bridge. _We now strike the Via Tusculana or Frascati Road._
